Not available outside your network - Remote Access

Hi,

I dont seem to be able to connect my ps4 to the media server as it says the media server and device are on different subnets.

i have the linksys router WRT 1900AC Smart WiFi.

i have tried to add a new port Forwarding , still server is not accessible..........

could you please assist, as at the moment i can't seem to find a solution.

Thanks in advance.
